No, they are not part of the name, see Art. 46.1. Also, authorship
does not make a name unique. One and the same name may be rendered
with different authorships in different publications, without this making a difference. Also, to some extent, loosely speaking, there
may be differences even though the authorship is the same.

***
If precision is the order of the day, Pinus pinus is not a
tautonym. It would be a tautonym if it existed. However, it cannot
be validly published, so it cannot become a name (or a tautonym).

It would, provided these are viewed from the same taxonomic
viewpoint. If this is not assured, it could also be the same taxon.

No, this last is not possible, see Art. 26.
Autonyms do not have authors.

Yes, on the "subsp." I do not see support on it being wrong to cite
authorship of a species name; in most circumstances it is superfluous,
but I can think of cases where it would be desirable.

Sorry for the lecturing,
